[Chimera-users] Measuring angles between atoms pairs

[Yasser Almeida Hernandez]

Dear Chimerians...

I'm running an analysis about H-bonds geometries in several models.

I need to measure the distance of a H-bond and the angle formed with a third atom bonded to one of the H-bond atoms.
How could I do that in a python IDLE/script?

In a more general way, how could I measure the angle between three atoms linked by a bond o pseudobond?

Thanks in advance

Yasser
